Patented March 3, 1908.

I To all iuhom it may concern:

Be it known that I, FRANCIS ELDRED LODGE HARRIS, a subject of the Kingof- Great Britain and Ireland, and resident of Alderley Edge, in thecounty of Chester, England, architect, have invented a'certain new anduseful Improved Apparatus for Cleaning Large Panes of Glass.

This invention relates to a new or improved a paratus for cleaning largepanes of show cases and the like tho ugh it may be applied to smallerpanes, the objectbeing to remove the water of condensation also whichmay form upon either the inside or the outside of the pane.

My invention will be fully described with reference to the accompanyingdrawings in which Figure I-is a transverse vertical section of anapparatus constructed in accordance with my invention while Fig. 2 is apartial plan of same partly in section.

In carrying out my invention I arrange either at the inside or outsideof the pane a, as may be required, and at either end or side of thelatter a suitable guide I) of wood or metal or a combination of each,such guide greferably having a longitudinal groove 0.

Xtending across the wlndow I employ a lath, bar'or rod (1 of a suitablecharacter and formed of wood or metal or a combination of each or ofother material or materials most suitable for the purpose, the frontedge e of which projects towards the window pane leaving a small spacebetween it and the glass a. This lath may have suitably secured to i itat its front edge a sheetor pad of felt f or other suitable materialwhich is preferably arranged upon a base 9 ;of india rubber or otherelastic or resilient substance and which is adapted so as to presstightly against the window ane and yet to give way to an inequalities ofthe latter. The pad of felt and rubber may be secured to the lath by thefree ends of each being passed into a groove formed at the front edge ofthe lath the required grip to hold it in place being secured by acovering strip 0', through which ispassed screws 1', bolts or the like.ends the lath is provided with metal studs is as those used in shopwindows,

At thewhich extend into the grooves 0 of-the vertical guides b and forthis purpose such ends are protected by metal plates Z to reduce wear,the studs being secured thereto or formed integral therewith. Throughthese studs pass the supporting and pulley cords m.

The cords are not passed directly through the studs but as will be-seenby Fig. 1 they. are passed indirectly through so as to act as a supportfor the la'th and at the same time by the top and bottom portions of thecord not being in alinement to cause the felt ad to be kept ti htlyagainst the window w en the cord is puIled for cleaning purposes.

The lath or rod d is suspended by the cord or rope, chain or the like mat each end, each rope or cord passing overa guide pulley or pulleysarranged in or adjacent to the guides and terminating in counter-balanceweights n adapted to rise and fall in a casement 0, if-

dry as will be seen from the broken lines in Fig. 1 and in whichposition it is held by the counter-balance weights n. By pulling thering or handle secured to the cords m or by winding the drum or winch"at the lower end of the pane the rubbing edge of the pad is immediatelybrought in contact with the face of the glass 0 by a slight lever actionset up by the position of the ropes or cords in passing through the lathas previously described and is brought down the face of the glass so asto clean the window or remove-water of condensation, while on releasingthe handle the counter-balance weights pull the lath to the top of theglass again. This operation may be repeated as often as necessary.

What I claim as my invention and ,desire to secure by Letters Patent isAn apparatus for cleaning glass comprising a lath, a pad-arranged at theforward edge of the lath, brackets in each large panes of v end of thelath provided with reduced extensions, eech extension being providedwith In testimony whereof I have hereunto set three transversely, alininopenings, guides myhand in the presence of two witnesses.- arranged ateach end of t e lath said guides v v I having grooves to receive thereduced exten- F.

5 sions of the brackets, and operating cords for Witnesses:

the lath, a cord passing continuously through MABEL LEE, the eliningopenings of each bracket. J AS. STEWART BROADFOOT.
